[dojox/form/Uploader] use iframe can only upload file once

[yisuren]

when i use dojox/form/Uploader and under IE browser, the upload is use iframe. What confuse me is that ,I can upload the file only one time whether the response is success or failed.

so I do some dig into _IFrame.js I found that in the iframe ajax callback.

domConstruct.destroy(sendForm);

I think that is the reson why the upload button dose not reaction click event when uploaded once

should the code be modified as following?

sendForm.appendChild(n);
=>
sendForm.appendChild(lang.clone(n));
